k12 steel wheel

as above , my car has just been hit , and bent the rear steel wheel . i have submitted a claim to my insurance company , since the bumper has been damaged to , i have put on the space saver but would prefer a 15 " steel on . its a 2009 k12 . could be 3 weeks till the insurance gets sorted and i use my car every day for work .any money i spend will not be reimbursed .

thanks .
